Alerts and Notifications

Chapter 6 61

Introduction

The Digi CM unit can be configured for system alerts and notifications. It sends

email messages when the number of system log messages reaches a certain

value or when an alarm message is detected in the serial port data. The Digi

CM unit uses SMTP (Simple Mail Transfer Protocol) for sending the

notifications. To use SMTP, the system administrator must configure a valid

SMTP server for sending the emails. The Digi CM unit supports three types of

SMTP servers: SMTP server without authentication, SMTP server with

authentication, and POP before SMTP.

The Digi CM unit also supports SNMP (Simple Network Management

Protocol), a protocol used to manage a network and monitor devices on a

network. System and port alerts can also be sent using SNMP traps. The Digi

CM unit supports both versions 1 and 2 of the SNMP protocol. The main

function of SNMP on the Digi CM unit is to allow a system administrator to

query remote devices for information.
